Misfire 94' Eagle Talon

This has me stumped I have a 94' eagle talon 1.8L with 124 thou miles the engine just went out of it (bearings) I got an engine from a junk yard and put it in double checked timing getting fuel to every cylinder every thing is hooked up compression is about 130 in all 4. Got the car running but it missfires it had good spark in 1 2 and 3 with no spark on 4 got new plugs and wires cleaned the distributer cap and rotor, coil and connecters. Tryed it agian 2 3 4 fired but with misses and no spark on 1 I changed the distributer completely and same problem its acting like the coil is breaking down or something of that nature but the coil on it is contained inside of the distributer and I changed that could this be a computer problem or hopefuly a senser car ran good befor the engine blew (just had fluxuating oil pressure) just need a little help electronics arent my strong point any help is appreciated
